Has anyone tried to use a mirror and bubble level as Richard Hubbard described in his book "Boater's Bowditch"? He describes using a thick glass mirror with a plywood back and thumb screws for leveling. What is the down side of this and what kind of errors would you expect? Is the error all in the level or are there others? Thanks. Jim Foley
